| | [code=c] #include<stdio.h> #include<stdlib.h> main() { char a[32],*a1,b[64],*b1; a1=&a[0]; b1=&b[0]; a1="hellohellohellohellohellohello" ; printf("\n contents of a1: %s\n",a1); int i =0; for(i=0;i<=31;i++) { printf("%c",a[i]); } } [/code] So why does printf ("%s",a1) work correctly while printf("%c",a[i]) display junk ?
